This invention relates to supporting andv 'swinging mechanism' of transom windows or vto provide improvements'in appearance and operation of such structures. v

figure 1 is a fragmentary front view of a transom overa door showing a preferred location of a manually turnable knob by which transom-operating vmeans is adjusted. F ig.` 2 `is a sectional detail on the line 2-2`of Fig. 1. i 'I Fig. 3 isa side view of the transombperating means, the part shown in section being taken on the line 3 3 of Fig. 1.

Fig. 4 is a sectional view partly broken away taken transversely through the transom, as indicated by the line 4-4 of Fig. 1.

Fig. 5 is a perspective'detail of the trany som-operating means.

Fig. 6 is a detail partly in section showing l v -in the' door frame structure by Vhaving attached to its outer side faces places or arms the mounting of a worm by means of which, through a worm' wheel and parallel links7 the transom is adjusted around its hinges, l l l lwhich arms respectively carry trunnions 18,

and a hollow shaft v19ppassing through the or pivots.

The transom operator herein disclosed is designed for mounting Vwithin a partition' post or door frame, in` Order to be out of view and require no change in the appearance of a door frame structure, except for the mounting of a small rotatable handle by' shaft 19 is preferably rolled from flatstock y and is provided at each end withprojecting'f vlugs 22 which fit corresponding apertures which the transom is manipulated. It is generally common with transom operating means, whether exposed to view or concealed within a partition post, to transmit motion to the transom, both by thrust and pull. In

v`som operating links 24 and 25 are pivoted.

The shaft 19 isclamped between the arm'z-f-r 1.15 and link-connecting lever 23 Vby bolt '26 such cases`l unless the operating bars or rods are of suiificient rigidity and there is a long span between bearings, the operating means may not shift easily, due to a'tendency to bend or buckle. y v

In the improved construction hereindescribed, a light and easily manipulated mechanism is provided wherein parallel links are employed to shift the transom in both directions by a tension on one or the other of the links. A thrust action is avoided.

The invention is carried out by means of 1930. Serial No. 461,551.

a parallel link'structure in which the links are shifted in opposite directions by means of a worm which is turned by a handle eX- tending through the partition postv'and operates la worm wheel sector to which the" transom' operating links are pvoted.-

Figure 1 of the drawings shows. a door 1 'and transom window 2 mounted thereover in a frame structure, including the partition posts 3 and 4. The partition post 3 is hollow and receives the transom operator which includes a lower bent'metal support and housing 5 for the worm-v gearing at-the lowerend of the transom'operator and a supporting bearing 6 at the upper end of the transom op` erator, leach of which is attached by the screws 7 and 8 to a vertical channel member 9. `.The channel member 9i, and channel memby rivets 12 and are constructed vto removably receive the metal moldings 13. Y

The ,transom 2 is pivotally mounted with- 14and 15by means ofscrews16 and 17 ,and

bearing 6. Trunnion-18 is riveted to arm y14 and provideszapivotal support for one? y side of the transomiby extending into a bear- .ing thimble 2O seated in an aperture .21 in the door and transom frame. The hollow in transom supporting arm 154 and a diskshaped connecting lever 23 to which the tranriveted headed pins 29, passing throughslotsl 36in theupper endsl ofthe Vlinks 24 and 25.

'A downward pull on either. one-of the links will, therefore, result in rotation of shaftvl9 within its bearing 6' anda consequent ad- `ijustment of the transom because of the fixed fiber 10 form the partition post. These meml bers carry clips 11 which are attached thereto connection between the shaft 19 and the transom arm 15.

The links 24 and 25 eXtend downwardly from their pivotal connections with lever 23 to a worm wheel 31 near a transom-operating handle 32, the latter being at a convenient height for manual operation. rlhe worm wheel 31 is rotatably mounted upon a pin 32, supported in apertures in the side of housing 5 and is spaced from the walls of the housing by the collars 33. Worm wheel 31 has ears 34 to which the links 24 and 25 are pivoted by the headed rivets 35. rIhe worm wheel 31, includingthe ears 34 thereon, is a flat member having worm teeth 3G formed on the lower edge thereof. A worm 37, meshing with the wheel 31, is supported on its annular flanges 38 and 39 by a rivet 40 and bearing sleeve 41 respectively. The flange 39 has a squared socket 42 for receiving the square end of the handle stem 43. The handle stern passes through an opening in the molding 13 and is round in cross section where it passes through the bearing 44 attached to the molding 13. The handle 32 v vis prevented kfrom moving endwise through the bearing 44 by a washer 45,.forced on to the squared end ofthe handle stem.

lhen the transom operator is installed, the center of the shaft 19, around which the transom swings, and the center of the pin 32 for the worm wheel 31, are at such distance apart 'that the slots 30 at the upper ends of links 24 and 25 are below the pivot pins 29, Figure 3. Thus in the operation of the device,

' the turning of handle 32, in either direction,

will result in a downward pull on one or the otherof the links and through such pull the motion is transmitted to the transom, swinging it on its pivots. If the transom is not centrally pivoted and, therefore, not substantially balanced on its pivots, the motion of the transom, when permitted by operation of handle 32, would still merely result in tensioning one of the links 24 or 25. The arrangement of the lost motion connection between the upper ends of the links and the lever 23 is such that a thrust is not transmitted at any time through one of the links to the transom.

Although but one specic embodiment of this invention has been herein shown and described, it will be understood that details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. A casernent structure including a frame, said frame being hollow and including a vertically disposed channel barfor supporting operating mechanism, a bearing secured to the upper end of said channel bar, a window pivotally supported in said frame and carrying a shaft extending through said bearing,

a lever on said shaft, a support and housing for worm gearing secured to said channel bar and spaced downwardly from said bearing, worm gearing in said housing and including a worm wheel, a pair of links pivotally attached to said worm wheel at their lower ends and pivotally attached to said lever at their upper ends, and a handle for operating said worm gearing.

2. A easement structure including a frame, said frame being hollow and including a vertically disposed bar for supporting operating mechanism, a bearing secured to the upper end of said bar, a window pivotally supported in said frame and carrying a shaft eX- tending through said bearing, a lever on said shaft, a support and housing for worm gearing secured to said bar and spaced downwardly from said bearing, worm gearing in said housing and including a worm wheel, a pair of links pivotally attached to said worm 'wheel at their lower ends and pivotally attached to said lever at their upper ends, said pivotal connections being arranged to provide for lost motion whereby each link transmits motion by pull only, and a handle for operating said worm gearing.
